Abstract
The comparison of characteristics of anodic dissolution of copper М1 with ultra-micro-grained struc- ture in a comparison with its coarse-grained analog under conditions of electrochemical machining of metals (ECM) has been carried out. The influence of material structure on ECM characteristics (machining rate, localization coefficient, surface finishing) in chloride and nitrate solutions with different concentrations is shown. It is shown that the influence of material structure is much higher in passivating electrolytes (nitrate solutions) due to the features of surface oxide films shaping.
